Since the fixed nozzle 5 for pouring the metal is provided separately from the flat spray nozzle 1, the configuration is complicated and the installation space becomes large.In addition, the flat spray nozzle 1 has to be rotated in order to achieve optimal stirring. In addition, the installation location of the fixed nozzle 6 is limited, and the opening area is also large, which reduces the flow rate of pouring and takes time to prepare the beverage. In addition, especially when producing cold beverages, the entire process of stirring and pouring is performed using a 7-rat spray nozzle, which takes more time to prepare than hot beverages, and when adding water, the sprayed water hits the ice. It was scattered outside the bonito and contaminated the surrounding area.

In order to solve this problem, it is conceivable to separately provide a cold water nozzle with a large opening area, but this would be inappropriate since the raw material stirring device would have a complicated structure.

In view of the above-mentioned problems, the present invention provides a device for stirring raw materials in a cup of a cup-type vending machine, which has a simple structure, saves space, shortens the time required for preparing drinks, and has a high degree of hygiene without scattering of drinks to the surrounding area. It is something to do.

Means for Solving the Problems In order to solve the above problems, the raw material stirring device for a cup-type vending machine of the present invention has a needle inserted into a nozzle for injecting drinking water into a cup, and a needle that is inserted into the nozzle in the axial direction of the nozzle. The device is configured to include a driving means for moving in multiple stages.

According to the above-described structure, the present invention first injects drinking water into the cup into which the powder raw material has been introduced in a shower-like manner by moving the needle downward from the nozzle opening, and then pouring the drinking water into the cup. By moving the nozzle upward until it is flush with the opening and injecting drinking water, the drinking water is sprayed into the cup from the tip of the nozzle with a small opening area. Furthermore, by storing the needle deep inside the nozzle, the opening area of the nozzle is expanded again, allowing a large amount of drinking water to be injected.
